Reply To: Translating "Written by" on posts

Finally got it to work.
Adding my language as you suggested did not wok in my case.
What worked is deleting English lang from here http://prntscr.com/7l1unz and adding English lang again.
Re-scan English, Edit, translate Written By, generate mo-file and voila it works!
Just wanted to reply back in case someone runs into same issue.
Again, thanks for your help!
